To all whom it may concern:

Be it known that I, ARTHUR D. Snnonsnv, a subject of the Emperor of Austria-Hungary, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvementsin and Relating to Inking Mechanism, of which the following is a specification.

. This invention relates to a printing apparatus, more particularly to -the devices for inking type or embossed surfaces for printing purposes.

One object of means adapted to ink the type of a printing press in such manner that the printed impression therefrom will have the appearance usually effected by a ribbon such as in a typewriter.

Another object of the invention is to pro vide an improved ink distributing roller for inking the type of a printing press whereby manually operated typewriter effects can be obtained. 7

With these and other objects in view, the invention consists of the parts and combination or combinations of parts hereinafter described and set forth in the appended claims.

For the purpose of illustration, I have in theaccompanying drawings shown and herein described one embodiment of my invention.

Referring to'the drawing, Figure l is an elevation of an inking means embodying my invention, and a portion of the form of printing press to which said inking means may be applied. 7

Fig. 2 is a side elevation of the parts shown in Fig. 1.

Fig. 3 is a section on the line 3-3 ofFig. 1. i

Fig. 4 is a plan view of the ink distributing device. i

Fig. 5 is a view of the ink supplying device.

Figs. 6 and 7 are detail views- In the drawings, A indicates, as an entirety, a printing press which may be of any preferred form of construction, a. portion only of the press being shown. In the construction of press herein chosen to be illustrated, there is provided a bed, which; may consist'of a cylinder or drum A, to carry ype l3 upon its surface. In usingthe term type herein, 1 wish to cover any and all forms of devices, such as type, plates, slugs,

the invention is to provide INKING MECHANISM.

Specification of Letters Patent. l a,fi]@11ted Bi 3 jggj- Application filed December 8, 1916. Serial No. 135,726.

etc., from which impressions can be made, it being entirely immaterial, so far as my present inventlon is concerned, what particular form of printing devices are used. The type or printing devices B may be secured to the drum in any suitable manner, but preferably by are members 6, which may extend through openings in the type andbe detachably se-v cured at their opposite ends to engaging members a, a, on the drum A.

The drum A is preferably fixed to a shaft B. The opposite ends of the shaft B are mounted in suitable bearings provided in the walls Zconstituting the frame of the printing press. At one end, the drum A may be pro vided with two gears 3, a, one of which, 3, meshes with a gear 3*, thatforms an element of suitable power transmitting devices to rotate the drum A. with and drives a pinion 4 which in turn drives the inking devices 5, as will be later set forth. v

6 indicates a frame for supporting the ink ing devices 5. The frame 6 preferably comprises a pair of plates 6 6 which are rigidly connected in spaced relationship by a plurality of tie rods 6". The opposite ends of the rods 6 may be reduced to form shoulders against which the inner faces of the plates 6 6 rest. The inner side edges of the plates G are formed with slots 6 which receive pins 2* projecting from the outer faces of the press frame 2 to detachably connect the frame 6 to the frame 2. The pins 2* may be formed with screw threads to receive clamping nuts 6 by which the plates 6 may be securely fixed to the frame 2.

Of the inking devices 5, 5 indicate an ink supply or fountain roller, which is preferably formed of suitable material, such as felt, capable of absorbing and maintaining a relatively large quantity of printing or transferring ink. The shaft 5 of the ab sorbent roller 5 is mounted in suitable bearings 5 preferably provided on the inner faces of the plates-6 The upper walls of the bearing 5 are open to permit the easy removal .of the roller shaft 5?. Near'one end, the shaft 5*" 'hasfixed to it a gear 5, which meshes with and is driven by the gear 4. The gear 4 is mounted on a stud shaft 4*. The inner end of the stud shaft l is mounted in abearing provided on a bracket The other gear, .4, meshes sov . shown at 7".

4 the outer end of the shaft is mounted in a bearmg provided on the ad acent wall 6*. v 7 indicates the inking device which applies orcoats the type B with ink and at the same time imparts thereto the property of causing the type B to imitate ribbon effects such as are'produced by typewriters. The device 7 preferably comprises a roller formed of a core of suitable material, the surface of which may be embossed to imitate a typewriter ribbon, or provided with one or more layers of fabric, or wire mesh material as The fabric or wire mesh material may be in theform of or applied to a belt running around the roller 7 and one or more guide rollers, or the fabric may be directly applied to the surface of the roller. As shown in the drawings, the fabric 7 is wrapped around the core 7 several times, care being taken to prevent any uneven surfaces in the circumference of the roller. Preferably the ribbon or fabric is wrapped twice around the core with its ends terminating at substantially the same point. fabric 7 may be of silk or other material and preferably woven with a mesh-corresponding to that of the ribbons usually used on typewriters. The roller 7 normally rests inengagement'with the fountain or supply roller 5 and in a position to engage with v and ink the type B as the drum A rotates.

The roller 7 receives ink from the fountain roller 5 and then applies it to the type B.

- slidably receive 7 a plate 8.

Where the core of material comprising the roller .7 is formed of felt, the ink may be supplied to such core and it in turn supplies the ink to the inner surface of the fabric. In carrying out its function, the fabric 7 imparts to the'surface of the typeB an impression of its weaving and the type B in turn transfers such impression in printing onto the papers or cards being operated upon, so that the latter have the eye appear-- ance of work or typewriting actually done on a typewriter by a typist.

I prefer to provide means, indicated as an entirety at 8, for supporting the ink applying roller 7 in a manner which permits it to be moved or adjusted toward and from the printing devices and also permits it to be moved or adjusted toward and from the fountain roller 5, said means providing for either of these adjustments independently of the other. Of these supporting means, 8*, v

- desired distance.

The

8 indicates an elongated slot which the shaft 7 of the roller 7 rotates and slides endwise, as will be later described. The opposite side edges of the plates 8 are grooved to receive the walls of the slots 8. The lower end of each rocker 8" is provided with a foot piece 8 which is preferably disposed between the free ends of two alined screws 8 The screws 8 are mounted in screw-threaded evenings formed in spaced brackets 8 whici are fixed in any well known manner to the outer face of the adjacent plate 6 Both screws are tightened against the foot 8 and thus hold the rocker 8 fixedly in any desired position. To adjust the rocker 8, one screw 8 is backed and the other screwed up, thus causing the rocker 8 to move about its pivot the The effect of this operation will be to move the roller '7 toward or from the printing devices B, accordingly as the screws 8 are moved in one direction or the other.

' 9 indicates an arm carried by each rocker 8.' Each arm 9 extends longitudinally of the rocker and is provided at its free end with an inwardly turned support 9. The support 9 is formed with a threaded opening to receive an adjusting screw 9 which is preferably disposed in the plane of the ad jacent bearing plate 8 so that its free end can engage therewith, The screws 9 serve to prevent the bearing plates 8 for the roller-7 from sliding outwardly in the slots 8, and to maintain the roller in operative engagement with the fountain roller 5; the screws 9" also serve as adjusting devices to move the roller 7 toward the roller whereby the former may be caused to bear a ainst the roller 5 with any desired degree or pressure. The longitudinal axis of each slot 8 preferably extends in a direction which is coincident with plane cutting the axis of the rollers 7 and 5, so that the adjustment of the former will take place in that p ane. The arms 9 are curved or otherwise shaped, as indicated at 9, to extend around the shaft 7 to permit the latter to extend outwardly beyond their bearings a considerable distance. Each arm 9 is preferably pivoted 9 to the adjacent rocker 8. This form of construction permits the arms 9 to be moved outwardly (see dotted lines in 2) when it is desired to remove the roller 7.

The shaft 7' is preferably extended at its opposite ends sov that in addition to its rotary movement,'it may be caused to recipro- Cate axially in its bearings by the following devices chosen as one form of construction for effecting such movement: 10 indicates a sleeve fixed to the shaft 7 between one end of the core 7'and the adjacent plate 6. 10, 10 indicate two grooves formed in the sleeve. These grooves are spiraled in opposite directions and the opposite end of each groove merges in or connects with the op posit'e ends'ofthe other groove to form one substantially continuous groove or cam. l0 indicates a shoe which slides in the grooves 10, and by its engagement with the side walls of the grooves, causes the shaft 7 to move or reciprocate longitudinally when it is rotated. The shoe 10 is supported by a bracket 10 which in turn is preferably fixed to the adjacent rocker 8. The shoe 10 is connected to the bracket 1O by a pin 10 which rotatably fits a bearing opening therein, so that the shoe 10", which is preferably elongated as shown in Fig. 6, may accommodate itself to the direction of the grooves 10. The pin 10 is preferably movable axially in its bearing opening to permit its removal from the grooves 10 but is normally pressed toward the bottom walls of the grooves by a coiled spring 10 interposed between the bracket 10 and a collar 10 that is fixed to the pin. At its outer end the pin carries a head 10* which engages the bracket 10 to limit the inward movement of the pin 10 When it is desired to rotate the roller 7 without moving it endwise, the shoe 10 is disengaged from the grooves 10 and placed in an annular groove 10* formed in the sleeve 10 near its outer end. When so arranged, the shoe 10 will prevent l0ngitudinal or axial movement of the shaft 7 By my invention I am enabled-to rapidly print from printers type, as well as other forms of printing devices, upon surfaces in a manner which gives typewriter ribbon effects. t will therefore be seen that by the use of a mesh material on the ink applying devices, printed matter, such as letters, substantially imitating individual work on a typewriter,can be produced in a rapid and economical manner. The fabric or section of woven material surrounding the roller serves to form a resilient surface for contact with the printing devices and operates to efficiently apply the ink thereto. My invention is advantageously adapted for use in connection with printing machines of the drum type, such as shown in the drawings; when so applied it simplifies the construc tion of the apparatus and permits it to be operated at a high rate of speed.

To those skilled in the art of making apparatus of the class described, many alterations in construction and widely differing embodiments and applications, of my invention will suggest themselves, without departing from the spirit and scope thereof.
